2 Claims.

The present invention relates to cleaning devices and more particularly to devices for cleaning the draft rolls of spinning frames.

The lower draft rolls of spinning frames, which comprise narrow rolls with longitudinal flutes, become fouled in normal operation by a wax-like material carried by the roving in its passage to the bobbin. When the rolls become sufiiciently fouled to interfere with proper grip of the roving, it is customary to clean them manually by picking the flutes with a sharp instrument. The cleaning operation, as thus practised, requires an inordinately large amount of time.

The object of the present invention is to provide an apparatus by which the draft rolls may be quickly and thoroughly cleaned in a comparatively short time and to this end, the present invention comprises the apparatus hereinafter described and particularly defined in the claims.

In the accompanying drawing, Fig. 1 is an elevation partly in section of so much of a spinning frame as is necessary for an understanding of the present invention, with the preferred form of roll cleaner in operating position; Fig. 2 is an end elevation of the cleaner with the motor and brush removed; and Fig. 3 is a detail plan view of the cleaning brush.

The portions of the conventional form of spinning frame shown in Fig. 1 are the bottom rail 4, the bobbin driving mechanism 6, the bobbin 8, the guide board ID, the lower draft roll l2 and the upper presser roll I4, these rolls acting to feed the roving through the guide board to the bobbin. The roll I2 is fluted or corrugated, as shown in Figs. 1 and 3, and it is the purpose of the present invention to provide means for readily cleaning corrugations when they become filled.

The roll cleaning device comprises a platform I6, hinged at I8 to two vertical standards 20 which are provided with slots 22 to permit adjustable attachment to lower vertical standards 24. The upper and lower standards together form a supporting frame which may be varied in height by relatively adjusting the standards through the means of a bolt connection 26. Extending inwardly from each lower standard 24 is an angle piece 21 carrying a roller 28. The two rollers 28 are adapted to roll on the rail 4. The angular relation of the platform IS with respect to the vertical frame may be adjusted by means of a pair of links 30 and 32 pivotally connected respectively to the frame and the platform. One of the links is slotted and the two links may be held in adjusted position by a bolt 34.

The platform I6 carries a motor 36 which, for

convenience, may be similar in form to the usual type of hand drill motor. The mot-or is supported in the frame by means of a bolt 38 hinged at its bottom to the platform and a similarly hinged yoke 48 which receives the end of the bolt and is 5 secured thereto by a wing nut 42. The motor has a chuck 44 connected by a shaft 45 and a suitable coupling 46 with a beveled gear 48 in a gear box 50, which is supported on an extension of the platform overhanging the supports 20. 10 The gear 48 meshes with a beveled gear 52 which drives a Wire brush 54. As shown in Fig. l, the axis of the brush is inclined slightly from the vertical. The brush is of any suitable form having a central hub with radial stiff steel bristles.

The gears 48 and 52 are mounted on suitable shafts which are journaled in the box 50 in any usual orpreferred manner, the shafts and bearings not being shown in full detail.

As shown in the drawing, the platform is adapted to take a hand drill 36 of conventional form and since the tool may be quickly inserted into or removed from the yoke 40, it is available for other use when the roll cleaner is not in operation. To permit removal of the tool, it is, of course, necessary to release the chuck 44.

It will be observed that the adjustable frame permits the wire brush to be placed at the proper height regardless of differences in size or arrangement of the spinning frames. Moreover, the provision for angular adjustment of the platform with respect to the frame permits the brush to enter the space immediately under the roll I4 without being blocked by the guide board H).

In operation, the apparatus is mounted on the lower rail of the spinning frame and the parts are adjusted to bring the brush in contact with the roll, as indicated in Fig. 1. Both the draft rolls l2 and the wire brush are set in rotation, the cleaner being held stationary until the roll 12 has made one complete revolution. As shown in Fig. 3, the brush is of suflicient diameter so that it cleans each flute for its entire length. After a revolution of the roll, the cleaner is slid along for operation on the next roll. The total time for cleaning each roll is therefore substantially the time required for a complete rotation thereof. The machine may be run at normal speed and therefore a very large saving of time in comparison to the usual hand cleaning 50 method is effected.

Having thus described the invention, what is claimed is:

1. A device for cleaning fluted rolls of spinning frames comprising a vertical supporting frame, 55

a substantially horizontal platform adjustably mounted at the top of the supporting frame to permit some adjustment of the platform from horizontal position, means for securing the platform in adjusted position with respect to the supporting frame, a motor on the platform, the platform having an extension rearwardly of the supporting frame, a shaft near the rear end of the frames comprising a vertical supporting frame, a substantially horizontal platform adjustably mounted at the top of the supporting frame to permit some adjustment of the platform from horizontal position, means for securing the platform in adjusted positionrwith respect to the supporting frame, a motor on the platform, the platform having a gear box disposed rearwardly of the supporting frame, a shaft extending upwardly from the gear box, and a rotary brush on the shaft, the gear box and brush being of small height to afford access of the brush to the roll to be cleaned, the supporting frame having at the bottom a rearwardly extending member to support the device on the lower rail of a spinning 15 frame.
